abstract = {AimElucidating the potential suitable distribution areas of the katydid genus Gampsocleis Fieber, 1852 (Orthoptera: Tettigoniidae) holds significant implications for the conservation and sustainable utilization of ornamental singing insect resources.MethodsThis study utilized the Maximum Entropy (MaxEnt) modeling approach, integrating global occurrence records with CMIP6 climate projections, to analyze the distribution patterns of the katydid genus Gampsocleis under Shared Socioeconomic Pathways (Low emissions SSP 1-2.6, Intermediate emissions SSP 2-4.5, and High emissions SSP 5-8.5) scenarios, while investigating species-specific response characteristics.ResultsThe findings revealed that the katydid genus Gampsocleis currently occupies potential habitats covering approximately 14.90% of global land area (GLA), with core distributional hotspots concentrated in three major regions: East Asia, Southern Europe, and central North America. Under the low-emission scenario SSP 1-2.6, East Asian core populations maintained the strongest habitat connectivity with orderly poleward expansion, whereas the high-emission scenario SSP 5-8.5 induced significant stable habitat contraction and pseudo-expansion patterns in northern latitudes, characterized by non-viable temporary habitats. Concurrently, pronounced interspecific divergence was observed within Gampsocleis, with G. sinensis demonstrating robust range expansion capacity, while G. ussuriensis exhibited heightened sensitivity to climate forcing.ConclusionThis study provides a scientific basis for developing climate-adaptive conservation planning and serves as a representative case for understanding the response mechanisms of insect communities to global change.}
